COW Electrical Wiring Diagram

Below is a recommended procedure for wiring an exam room
to be controlled from the Trend Setter Refraction Desk Console.

1. Determine
Room Loads: From the following, determine the type and location of room loads
you wish to use.A. 3-Way Switching For Room Lights The
3-way circuit will accept 500 watts; 120-277
VAC fluorescent or 120 VAC incandescent
lamps.B. Dimming Control For Incandescent Lights. The
console will dim a maximum 500
watt load.
NOTE:If
incandescent lights are used in place of fluorescent lights in the
3-way
circuit above, the console can dim those lights also.C. Two 120 VAC Switched Outlets. Switches "Aux
1" and "Aux 2" supply 120 VAC
to loads not exceeding 250 watts each.D. Low Voltage Outlets. COW Industries has cable
and connectors available to attach
low voltage devices such as our
Projection Fixation Testing Center and Screentest II
or most low voltage accessories.
Normally, the electrician is not involved with this
aspect unless you wish to conceal the
cables within the walls.

2. Designate The Desk And Console Location. From
the room layout drawing above,
determine where the desk will be situated.

3. Install Power Outlet For The Console. Once the
desk location is established, install
a 120 VAC duplex outlet in the wall behind the desk. This
outlet should be centered
behind the desk and about 18" from the floor.

4. Install The Junction Box Component Of The Interface
Kit. The interface kit consists of
a 4-gang junction box with cover and a 5' interface cable.
Install the junction box in the
wall behind the desk next to the power outlet (step 3).
Following the wiring diagram
below, wire the room as determined in steps 1a through 1c.

5. Check The Completed Wiring With The COW Industries QUICK
TESTER.Use of the Quick Tester will confirm that the room is properly
wired, or point out problems.
This will insure a safe, trouble-free installation of the refraction
console.

NOTE: The desk is 32" x 60" with a recessed
back. This provides ample space to
accommodate
and conceal power cables and the junction box.
